Hawking, along with another scientist, I think it was Penrose, came up with the application of Quantum Mechanics to Black Holes. Among other things, this led to the realisation that matter that goes into Black Holes is not lost forever, because Black Holes give off radiation and can be considered to have a non-zero temperature. The temperature is inversely proportional to their size. Over a very long time (billions of times the length of the universe so far) they will evaporate, eventually disappearing in a flash that would be blinding if there were anyone left to see it.

What modern US president's first name was Stephen? Which famous scientist pubilicly ridiculed the ideas of dr. s chandrasekhar (carl safan, fred hoyle, stephen hawking, arthur eddington) ? I'm reading Stephen Hawking's "A Briefer History of Time". In it he says that antiparticles can be thought of as regular particles going back in time. Assuming that's true, it logically follows that antiparticles should have antigravity instead of gravity. Do they? How many books has Stephen King written, and what are they?
